I went looking for some backup info on my prefered finish here- Sunflower oil. Once again the search engines took me to Russ Fairfield's site:

a quote from the page:
"Any edible non-drying oil can be used as a coating on wood. Non-drying oils that are useful coatings for a salad bowl would be Mineral Oil, Sunflower Oil, any of the vegetable cooking oils, and pressed Walnut Oil. Choose the oil carefully, clean and renew often, because many of the vegetable oils and most cooking oils will turn rancid with time.
My preference is the Sunflower Oil (not to be confused with Safflower Oil) because it does not turn rancid with age, it has a pleasant odor, and it partially dries if I am willing to wait."
